Cannot join on Memo, OLE, or Hyperlink Object

Question

I have a basic table in an Access database. In that table, I have a 10-digit numeric field that is stored as Long Text (leading zeros are significant). I extracted the unique

Answer 1

You just have to convert the longtext to shorttext and the join will work

Answer 2

Use ANSI JOIN instead. It worked for me using

        SELECT A.A, B.B, C.C
           FROM aaa AS A, bbb AS B, ccc AS C
       WHERE A.B = B.ID
            AND B.C = C.ID

Answer 3

Access does not allow Joins based on Long Text fields. That's the "memo" it is referring to. I assume Microsoft's rationale is that basing a Join on a paragraph of text is unreasonable.

Answer 4

Try to convert the 10 digits numeric field stored as long text to short text. long text is for the memo that's why you're getting this error.

I had the same error resulting from LEFT JOINING a msSQLserver table view ON a local msAccess table, the field datatype was nvarchar(80000) in SQL server table and was auto-converted into Memo datatype when linked to msAcces so I had to convert it to nvarchar(25) from SQL server and refresh the table link to solve the issue.
